definately put him in the bag and let him float for atleast 15-20 minutes, i usually do more just to be safe. periodically take some of his bag water (or just use the cup he came in if you still have it) and dump a bit and add some of the new water to slowly adjust him to it. this should be done any time you cup/bag him and put him back in his tank, even if it's just a quick water change - better safe than sorry!
